Avoid hot compresses for sprains Acute sprains of the wrist, waist, ankle, etc. are common in people’s daily lives or a variety of physical exercise. Acute sprains often appear localized swelling, pain, activity is limited. Sprain some people always like to use hot towels, hot hot water bag hot compresses on the affected area, in order to reduce swelling and pain. In fact, this practice is wrong. Because the sprain local capillary rupture bleeding, blood stagnation and the formation of hematoma, if the hot compresses on the affected area, will make the blood vessels expand, increase the amount of bleeding. Some people sprain localized swelling is not significant, but after the hot compresses instead of swelling and pain, is this reason. After sprains, cold compresses should be used. Appropriate cold towel (towel dipped in cold water) and elevate the affected limb. Cold compresses can make blood vessel contraction, reduce local heat, reduce bleeding; elevate the affected limb can accelerate the return of blood, not to make the blood flow to the rupture of blood vessels and a large number of oozing, prompting hematoma dissipation. Avoid ignoring the splinters into the hand splinters into the fingers of few people care, but the light can occur inflammation, the heavy wound can be pus or even tetanus, so when the splinters into the splinters, if there is no splinter residue in the flesh, you can use iodine to disinfect the wound, or then clean gauze bandage. If there is a splinter in the wound, you should try to take it out and sterilize the bandage. If the finger is stabbed, swelling and pain, infection and pus, should be promptly to the hospital for treatment, if necessary, need to be injected with tetanus antitoxin injection to avoid tetanus. Avoid squeezing pus from sores and boils After suffering from sores and boils, you should ask your doctor to give you reasonable treatment: applying ointment externally, taking antibacterial drugs internally or injecting them. The boil should be treated by a doctor: applying ointment, taking antibacterial medicine or injecting antibacterial medicine internally. However, some people ignore the danger and try to squeeze out the pus and pus plugs (commonly known as pus head) from the sores by asking others or by themselves when the pus flow in the sores is only initially formed or when there is already a rupture but it is very small. As a result, some lucky people are cured because the pus and pus plugs in the sores are successfully squeezed out and drained, but many people have various complications when the sores cannot be squeezed out and drained because of the small ulcers, thick pus, and large pus plugs under forceful squeezing. In mild cases, the scope of local inflammation is significantly expanded, pain is aggravated, and the period of illness is prolonged; in severe cases, pus or pus plugs are squeezed into partially open small veins or venous sinuses in the pus cavity, and thus severe sepsis or septicemia rapidly occurs, and the patient, in addition to the occurrence of chills, high fever, and impaired consciousness, may also have multiple boils of generalized nature or one or several deep abscesses in the drive trunk and limbs, and some of which may have suppurative diseases of the brain, lungs, liver, and other important organs. In some cases, suppurative lesions of the brain, lungs, liver and other important organs may occur. If the sore grows in the dangerous triangle of the nose and lips, the infection can spread rapidly in the skull after being squeezed hard, resulting in cavernous sinus infectious embolism, and the patient can die soon. Therefore, patients with sores should not squeeze the pus at will. Avoid using cold water to soak frostbitten limbs in cold areas, folk have been used to soak frostbitten limbs with cold water treatment method, this method is unscientific, the relevant research workers through a large number of studies found that frostbitten by cold water soak, light is aggravated by frostbite, or can be disabled, so it should be abolished this unscientific practice. Positive practice is: in the limb frostbite freezing period, immediately with 40-42 ℃ warm water immersion rewarming, has been immersed to the nails or the skin appears flushed until. Warm water rewarming can reduce the degree of disability of frostbitten limbs. Even no disability. Animal experiments have proved that immediately after frostbite rewarming, tissue survival rate can reach more than 70%. Avoid fire baking frostbite In winter, the weather is cold, hands and feet are easy to frostbite, but avoid fire baking. Otherwise, frostbite aggravation, or even ulceration. Because of frostbite, the first vasoconstriction, and then vasospasm, impede blood flow, if the fire baked, or hot water, the surface of the blood vessels will expand, while the deep blood vessels are still in a state of spasm. Due to the poor blood return, the subcutaneous tissue is lacking in oxygen, and the metabolic products can not be discharged. It will make frostbite worse, and even ulceration. Therefore, frostbite avoid fire baking. After frostbite, the local hand rubbing or slowly warming is appropriate. Suppurative wounds avoid using gentian violet Skin trauma, easy to be infected with pus and ulceration. But applying gentian violet is not conducive to wound healing. Because, gentian violet (i.e., violet water) although there is a certain ability to kill, but because of its astringent effect, coated with a layer of scabs will form on the surface of the wound, it seems that the wound is dry, in fact, scabs under the accumulation of pus, the condition has not been mitigated, but instead of the infection to the deeper parts of the diffusion of the disease to aggravate the condition. Therefore, pus wounds should not be painted gentian violet. Gentian is suitable for fresh, superficial skin trauma. Avoid changing too often The body due to trauma or inflammation and the formation of wounds, the appropriate change of medicine, to maintain local cleanliness, is conducive to anti-inflammatory and healing. If the change of medicine is too frequent, it is not conducive to the regeneration of local tissues, affecting the healing of the wound. Because the healing process of the wound surface, the cellulose in the blood and leukocytes in the exudate on the wound surface to form a kind of film, covering the surface of the granulation tissue, only to protect the growth of the granulation tissue. In addition, in the infected wound surface of the rotten, suppurating tissue, also produces a special beads of substances, stimulate the growth of all kinds of cells needed, thus contributing to the healing of the wound. If the change of medicine too often, so that the protective film is difficult to generate, or will destroy the protective film, is not conducive to wound healing. Therefore, the change of medicine should not be too frequent. According to the amount of secretion. You can change the medicine once every two or three days.
